thanks, that worked!
but now i ran in a new problem.
I built the new initrd and rebooted.
The cloned system starts, all the messages rush by - i can't see errors - perhaps because my eyes are too slow
I can see loading of lvm modules as well as filesystem modules (reiser, ext3)...
After loading of USB-Driver (before init starts) something like
md: stopping all md devices appears
md: restarting system
i have no chance to really check the startup output for errors...
i don't use md at all ?! so can't imagine what that means...
Any ideas?
